Abstract (en)

[origin: EP1134466A2] In a lip type seal, a case (31) is tightly fitted and fixed to an inner circumferential surface of a housing (1) through gasket means (32e). A resin lip member (33) constituted by an inner circumferential part (33c) extending in a bent state from a diameter direction part (33a) and its inner circumference to a sealed space (S2) side and forming a seal surface between an outer circumferential part of a rotary shaft (2) and the resin lip member (33); a rear surface support plate (36) disposed to abut on a rear surface of the diameter direction part (33a) of the resin lip member; and a stopper (37b) with a rear surface supported to a support surface (13) of the housing (1) through a second resin lip member (34) and a second rear surface support plate (38) and the top end coming close to or coming into contact with a rear surface of the inner circumferential part of the rear surface support plate (36), are provided on the inner circumference of the housing (1). Therefore, deformation of the rear surface support plate (36) due to pressure acting on the front surface of the resin lip member (33) and the contact of the rear surface support plate (36) with the rotary shaft (2) with the deformation are prevented (Fig. 1). <IMAGE>
